Phosphate Test KitPhosphate is a very important parameter in fresh and salt water aquaria. High phosphate levels are often guilty of causing ugly algae blooms in all aquarium types. Incidentally, this can be rectified by the use of Aquasonics phosphate sponge.
In marine aquariums, phosphates can harm sensitive coral and cause the precipitation of calcium.
Phosphate levels should be monitored on a continuous basis.
Testing for phosphates will also enable you to determine the source of phosphates in your aquarium. For example, it is a good idea to test your source of freshwater and a sample of water made from synthetic salt.
Measures from 0.1 to 3.0ppm levels.
